The other day my 2020 Acer Predator Helios 300 started showing both artifacts after moving/switching windows and constant horizontal lines. The lines are not visible on white, but are on grey, and very visible on colors. The lines are horizontal and at regular intervals across the entire screen. Any insight would be appreciated. It's like some lines of the display are not updating properly.
